Wearable modules from an open workshop

Eight modules in the first batch: a hair clip with a face, light earrings, paired Link, an emotion keychain, a collar that feels who is behind you and more. They react to the body without a phone. Every schematic is public.

Workshop rules

Open it

Every pack says the warranty is void if opened. Open it. The case comes apart, the battery comes out, the firmware can be your own.

Copy it

Boards, firmware and 3D models are published under copyleft licences. Build copies and sell them under your name.

No app

A module needs no app, account or cloud. Sensor data stays inside the module.

No war

The workshop makes no camouflage and no weapon shapes. PAIKA modules are not sold to armies.

Two blinks

Every module blinks twice when it powers on. That is how you spot a PAIKA module on a stranger.
